To ctZZ whom it may concern/.-

Beit known that I, PAUL GEIsEL, of Roch-r ester, in the county of Monroe, vin the State of New York,` have invented new and useful Improvements in Potato-Diggers, of which the following', taken in connection with the accompanying drawings, is a full, clear, and

arrangement of the component parts of a pol my invention.

tato-digger, as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming part l l of this specification, in which like letters indicate corresponding parts in both views.

. Figures 1 and 2 are respectively a top plan and afront elevation, partly broken away and in section, of my improved potato-digger, the

receptacle for receiving the potatoes being shown only in Fig. 2.

As, preferably constructed my improved potato-digger consistsof aframe A, supporting-wheels B B, a movable screen C, a plow D, and chutes E EEz.` The frame A is of any desirable form, size, and construction capable of supporting the remaining parts of The wheels Bare usually mounted upon a revolubleaxle Z9, journaled in suitable bearings a,fprovided.upon the frame A. The screen C is `preierably formed substantially cylindrical, is arranged between the rear portions of the wheels B B at the rear of the axle b, with its axissubstantially parallel 'with the line of draft, and is actuated `by the supporting-wheels B B.` Said screen is generally supported in position by a spindle c, which is journaled in suitable bearings y. a', provided upon the frame A, is` arranged substantially parallel with the line of draft, and is iixed to the screen C by any suitable means, as a cross-bar c. The spindie c may be connected to the axle b by any desirable power-transmitting mechanism, as a worm-wheel and worm c2 b. The screen C is usually formed with` suitable perforations.4

screen C.

member d, as a foot-lever, pivoted to thel frame A and connected to said plow by any desirable means, as a lever CZ anda link cl2.

`The chutes E E are usually supported by the frame A, with corresponding extremities arranged within the screen C and their other extremities extended downwardly in opposite directions through the frontend of the screen C and laterally beyond opposite portions of the periphery of said screen, as best seen in Eig. 2. The extremity of the'chute E within the screen C is generally formed with length- `wise perforations e and supports a series of spring-arms e', which are arranged at substantially right angles with the perforations e,

are separated a greater distance than the ad- Ejacent sides of the perforations e, and are supported above said perforations and in :close proximity to the path of 'the teeth c3 in Ia plane substantially concentric with the overlying portion of the periphery of the The extremity of the chute E' within the screen C is preferably arranged be neath the perforations e of the chute E.

The chute E2 is usually supported at one side of the adjacent portion of the periphery of the screen C and extends in a downwardlylinclined plane from front to rear of my potato-digger.

Said chute is preferably supported atits upper front extremity by the outer end of the chute E, but may` be" otherwise supported, if desired. Theupper end of the chute E2 generally supports a suitable receptacle E3, which is held in position by a catch E4, of such construction that when the desired amount of potatoes are within. the receptacle E3 the catch is automatically forced from its operative position to permit the automatic rearward discharge of said receptacle along the chute E2. The catch E4 may be of any desirable form, size, and construction IOC weight.

and is here illustrated as consisting of a lever pivoted to the bottom of the chute E2 and having its upper end movable into engagement with the rear side of the receptacle E3 and its lower end provided with a suitable As soon as the receptacle E3 is filled with potatoes the weight of said receptacle and potatoes forces the upper end of the catch E4 from its operative position against the action of the weighted end of said catch. The chute E2 and the receptacle E3 are particularly applicable for my improved potatodigger but may obviously be dispensed with, if desired.

In the operation of my invention the plow D discharges the dirt and potatoes within the screen C. The small particles of dirt readily pass through the perforations of said screen, and potatoes, grass, and lumps of dirt are elevated by the teeth c3 and passed over the spring-arms e. The potatoes pass between the arms e' to the inner extremity of the chute E and are discharged at one side of the potato-digger into the receptacle E3. The smaller lumps of dirt pass between the arms e and through the perforations e in the chute E to the inner extremity of the chute E and are discharged at the oppositeside of the potato-digger. The grass and larger lumps of dirt are fed over the arms e by the teeth c3 ot' the screen C and are discharged into the chute E.

The construction and operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a potato-digger, the combination of a revoluble substantially cylindrical screen, a plow discharging into the screen, a chute having one extremity arranged within the screen and formed with perforations and its opposite extremity discharging beyond the screen, and spring-arms arranged above the perforations of the chute, substantially as and for the purpose described.

2. In a potato-digger, the combination of a revoluble substantially cylindrical screen, a plow discharging into thev screen, a chute having -one extremity arranged within the screen and formed with perforations and its opposite extremity discharging beyond the screen, and a second chute having one extreximity supported beneath the perforations of the first chute and its opposite extremity arranged at an angle with the iirst chute and discharging beyond the screen, substantially as and for the purpose set forth.

8. In a potato-digger, the combination of a revoluble substantially cylindrical screen, a plow discharging into the screen, a chute having one extremity arranged within the screen and its opposite extremity discharging beyond lthe screen, and a chute extending from front to rear for receiving the discharge from the first chute, substantially as and for the purpose described.

4. In a potato-digger, the combination of a revoluble substantially cylindrical screen, a plow discharging into the screen, a chute having one extremity arranged Within the screen and formed with perforations and its opposite extremity discharging beyond the screen, spring-arms arranged above the perforations of the chute, and a second chute having one extremity arranged beneath the perforations of the first chute and discharging beyond the screen, substantially as and for the purpose specified.
